will be stable, reliable, subject tov ignition at a du'cing Match-Composition Ingredients, of which the following is a specification.

The principal inflammable ingredient of ordinary match compositions is yellow phosphorus, but there is a great objection to its employment-in that it is highly poisonous to the workmen who handle it and who are Substitutes therefor have been tried, but the results generally have beenimsatisfactor in that the resulting compounds have either been unreliable, unstable, have required a high temperature to ignite them, have beenexplosive, or have f otherwise been unsatisfactory.

It isthe object of my present invention to produce a non-poisonous compound such as non-explosive, and low temperature.

In carrying out my as a substitute for the yellow phosphorus .1 compound produced by combining amorphous phosphorus, chlorid of sulfur, and 'a metallic sulfid. The precise proportions thereof employed is not of the essence of my invention, but as an example I may say that I have obtained good results from a compoundproduced by combining 10 parts (by weight) of the amorphous phosphorus, 8 parts (by weight) of the chlorid of sulfur, and 2 parts (by weight) of the metallic sulfid.

At the time the materials are mixed the chlorid of sulfur should be at a temperature of about 150 degrees Fahrenheit. The three materials are thoroughly mixed together, the phosphorus and the metallic sulfid first,'and the heated chlorid of sulfur afterward addedthereto, and as thechlorid of sulfur at the temperature mentioned comes into contact with the phosphorus and the metallic sulfid, there is a vlolent reaction; the mixture bursts into flame. and the reaction continues for some minutes. Thereafter I thoroughly'wash the compound, then draw ofl the surplus water, and drythe residue. The product is'a powder of varithe particular metallic sulfid employed. This material -may be iron, zinc, copper, antimony, or

If for instance copper sulfid be employed the result will of a greenish color, while if-zinc sulfid be employed the resulting powder will be of a grayish color. tained as above, and mix it in the proper proportion with one (.1' more inert friction and binding elements such as powdered glass, whiting, and glue, or other ingredients such' as are commonly employed in match head compounds, the said product taking the place of the yellow phosphorus commonly employed. -The final compound may be applied to splints or stems in the usual or any desired manner.

The manufacture of this composition may be carried on with impunity as neither the ingredients themselves nor their fumes are poisonous. The resultant composition is stable and reliable, non-explosive, and will ignite under friction at a low temperature. Moreovefthe composition ,is not injuriously affected by moisture, but on the contrary when again dried willignite as readily as \Vhat I claim is ducing a substitute for yellow phosphorus in the manufacture of match compositions which comprises heating chlorid of sulfur to a temperature of about 150 degrees Fahrenheit, and mixing the same with amorphous phosphorus and a metallic sulfid.
